Mathematical Hydraulics Of Surface Irrigation, Cheng-Lung Chen
Reports
The general hydrodynamic equations for a spatially varied unsteady flow in a prismatic open channel having an arbitrary cross-sectional shape can be derived from the equations of continuity and momentum. The assumptions based on the general concept of hydrodynamics and the theory of shallow water is introduced. The mathematical models in the surface irrigation can be formulated by these equations of motion with the appropriate initial and boundary conditions prescribed at the singularity point (the origin in the x, t-plane) and at x = 0. Therefore, the flow in the surface irrigation must be described by solving the boundary-value problem …

The plan for the Central Utah project involves a diversion of water from streams in the Uinta Basin in the Upper Colorado River Basin to the closed Bonneville Basin in Central Utah and other associated water resource developments in both basins. Construction of the initial phase of the project was authorized by the Colorado River Storage Project Act of April 11, 1956 (70 Stat. 105).
The ultimate phase will expand on the initial phase development. Its purpose will be to increase the transbasin diversion to the Bonneville Basin and to provide water for replacement and additional use in the Uinta …

Graphical Solutions To Frequently Encountered Fluid Flow Problems, Roland W. Jeppson
Reports
Introduction
Graphical methods are often used by engineers to solve frequently used or complex formulas which require trial and error solutions. Perhaps the best known graphical tool used by the engineer is the slide rule, but anyone familiar with its use will recognize its limitations both in time and accuracy. For many problems which involve many repetitive computations high speed digital or analog computers are the most effective tools for solution. There are, however, many problems requiring considerable engineering time for slide rule solutions where solutions are not justifiable on computers. The use of nomograms for such problems is desirable. …

Construction, Instrumentation, And Preliminary Verification Of A Physical Hydrologic Model, Donald L. Chery Jr.
Reports
From theoretical consideration involving a rationalized dimensional analysis of the rainfall-runoff phenomena, dimensionless products of the pertinent variables are derived. These dimensionless products guided the design and construction of a rainstorm simulator and topographic model. The design and construction of these two basic elements of the physical hydrologic model are described. A description of the instrumentation and several relevant calibration tests is followed by a discussion of two preliminary verification test sets. The tests indicated that some necessary refinements in equipment and instrumentation were needed before more precise experimental data could be obtained. Further, the tests produced results which encouraged …
Water Vapor Measurements Using Infrared Absorption, Duard S. Woffinden
Water Vapor Measurements Using Infrared Absorption, Duard S. Woffinden
Reports
Man’s attempt to control the amount of available water has taken two approaches, i.e., weather modification and water storage through the use of man-made reservoirs. In either case, it is necessary to ascertain the water vapor content of the atmosphere. In the case of weather modification, if the water vapor content is insufficient, it is futile to attempt to start precipitation. In the case of reservoirs, it is important to know the evaporation rate since it has been demonstrated that some reservoirs provide a net negative contribution to the total water supply by increasing the normal evaporation losses. Any attempt …

The D.M.A.D. dam and reservoir are located on the Servier River northeast of Delta, utah, and serve as a stroage reservoir for the winter and spring flows of the Sevier River below Sevier Bridge Reservoir. The D.M.A.D. dam has been constructed with two outlet works, one for feeding Canal "A", which serves the Delta and Melville Irrigation Companies, while the other canal serves the Abraham and Desert Irrigation Companies.
A gaging station located along Canal"A" has been used for many years to obtain flow measurements. The gaging station measurements appeared to be very inconsistent, and consequently, in 1963 a study …

Reports
The calibration of small Parshall flumes for measuring flows ranging in magnitude from 0.1 to 1.1 cubic feet per second (cfs) was accomplished by A. R. Robinson (1960) at Colorado State University. The purpose of Robinson’s investigation was to accurately calibrate and standardize the design of small Parshall measuring flumes. The rated flumes were constructed of galvanized sheet metal. Data was collected for Parshall flumes having throat widths of 1-, 2-, and 3- inches. Calibration tables or curves were prepared for both free and submerged flow. The dimensions of the Parshall flumes rated by Robinson are shown in Figure 1. …

Reports
The primary objective in this study was to ascertain the validity of the method of analyzing submergence developed by Hyatt (1965) in a standard 2-foot Parshall flume. The method of analyzing submergence was first developed for a trapezoidal flume (Hyatt, 1965), was later verified for a rectangular flume (Skogerboe, walker and Robinson, 1965), and has been shown by the authors to be valid for small Parshall flumes (Skogerboe, Hyatt, Johnson, and England, 1965). In view of previous findings, it was felt the method would also be valid for large Parshall flumes, and for this purpose the 2-foot flume was selected. …

SCOPE AND PURPOSE OF INVESTIGATION
The discharge occurring in an open channel can be measured by placing a constriction in the channel. Flumes are commonly used as constriction in open channels. A flume is a specially designed and calibrated section built into a channel, the physical properties of which allow the calculation of the discharge. The narrowest section of the flume is usually called the throat. The velocity of flow through the throat, for any given flow rate, increases with a decrease in the flow depth. The ideal condition for measurement of discharge is a throat sufficiently constricted to produce …

Need and Importance of Study
Utah's problems of water use and water supply are becoming increasingly important. They are also becoming increasingly complex as competition for our water resources becomes more keen among various types of uses. In the formulation of plans for sound and efficient use of water it is essential to know the characteristics of occurrence and use of water supplies so that requirements can be balanced most effectively and economically against supply. This ordinarily requires basic hydrologic data to determine relations among climate, water losses, and water yield from watersheds.
Such data are often unavailable - especially …

The purpose of this research project was to calibrate the slide gates used by the D.M.A.D. Company (Delta, Melville, Abraham and Deseret Irrigation Companies). These gates, which number more than 600, are located throughout the distribution system. Each gate is placed in a concrete box 4 feet wide, 3-1/2 feet deep and 4 feet long. The structure is used as a means of diverting the water and is also used as a measuring device.

Aerial Application Of Evaporation-Reducing Chemicals, Development And Evaluation Of Equipment And Techniques, C. Earl Israelsen, Vaughn E. Hansen
Reports
Aerial applications of both liquid and powder evaporation retardants have been made in parallel strips on large lakes for purposes of comparison. Films formed from powder spread more rapidly than did those from liquid, but usually both films ultimately spread to approximately equal widths and had the same degree of compression as determined with indicator oils. Evaporation retarding materials with large numbers of particles having diameters smaller than 75 microns are greatly affected by the wind. As the chemical is dispensed from the airplane. the fine particles drift with the wind and in some instances are carried onto the land …

Of all the natural resources with which Utah has been endowed none is more vital to the social and economic well-being of the people than it water resource. We cannot manufacture water. We have found no acceptable substitute. Not one more drop of water is available for our use today than was available to the pioneers. Yet water uses and water demands have multiplied over the years. Since we can do little to change nature's water allotment to Utah we must learn how to utilize our existing supplies more judiciously. This means devoting increasingly more attention to problems of water …
